After Muhammad Shah's death in A.D. 1445, his son, Alauddin Alam Shah (reigned 1445–51), succeeded him to the throne of the Sayyid Dynasty, the fourth in the line of five dynasties that comprised Delhi Sultanate that ruled from 1206 to 1526.
Alauddin Alam Shah was more inefficient than his father. Such was his fondness for gratification and aversion to work that he abdicated the throne in favour of Afghan Buhlul Khan Lodi (reigned 1451–89), the governor of Lahore and Sirhind, in 1451 and retired to Badaun (now in Uttar Pradesh), where he died in 1478.
Alam Shah’s only claim to fame lies in the field of architecture. He constructed his father’s tomb which is located in the Lodhi Gardens in central Delhi.
He lies buried in a tomb in Badaun in Uttar Pradesh where his mother was also buried. The tombs of Alam Shah and his mother are an Archaeological Survey of India (ASI) protected monument.
